STOP AND WASTE COCK.

SPECIFICATION forming part of LettersrPatent No. 276,431, dated April 24, 1883.

` Application filed March 16, 1883. A(No model.)

To all whom it may concern Be it known that I, JOHN F. LAMPING, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Stop and Waste Cocks; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specication, and in which- Figure l is a perspective view of my improved stop and waste cock. Fig. 2 is a longitudinal vertical section, and Fig. 3 is a crosssection of the same.

Similar letters of reference indicate correspondin g parts in all the figures.

My invention has relation to that class of stop-cocks having a small waste-openin g, which is closed in opening the cock, andvice versa; and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates a chamber having two tubularnecks,`

B and G--one at each end-diametrically opposite each other, and a similar neck, D, at the top, at a right angle to the others. The outer end of the one of these necks is screw-threaded upon the outside and fits into a screwthreaded tube, E, which is adapted to be inserted into the vessel to which the cock is to be applied, while its inside forms a valve-seat, F, for an elastic conical valve, G, which is adjustably fastened upon the screw-threaded end of a valve-stem, H, by means of a cap, I, litting over its base, and a nut, J. The neck C is screw-threaded upon the outside to adapt it to receive Whatever kind of nozzle orftubing it may be desired to fasten to it, that neck forming the outlet for the iiuids drawn through the cock. The inner end of the valve-stem H forms a yoke, K, which, with a'plate, L, secured upon the same -by means of screws M, clamps around a double crank, N, which turns ,in a bearing, O, formed by two corresponding recesses in the inner surfaces of the yoke and the plate. This crank is formed upon the lower portion of a stem, P, passing down through the upper neck, D, and having a flange, Q, above the crank, which rests `and turns upon a correspondingly-shaped seat, l, and being held in place by an annular packing, S, in the neck D, which also serves to make the stem tit tightly in the neck. A metallic ring, T,.is placed upon Vthe top of this packing, and is held down by a sleeve, U, fitting upon the stem inside the Ii'eck. and held in place by a screw-threaded cap, V, having a central opening, W, through which the upper end of the stem projects, and fitting over the upper screwthreaded end of the neck. The lower end of sleeve U is cut away for one-half of its circumference, allowinga pin, X, projecting from the side of the stem to turn one half-revolution in the space Y thusleft open, and the stem with it,

while the sleeve is prevented from turning by a locking-pin, Z, inserted into a hole formed by a semi-cylindrical recess, a, in the side of the sleeve, and la similar recess, b, in the inner side of the neck. The lower end of the stem below the double crank Nforms a crank, c, of less eccentricity than crank N, which lits into la hole, d, in the inner end of a valvestem, e, which passes out through a wasteopening,f, in the side of the chamber. This openingforms a screw-threaded sleeve, g, forming a seat for an elastic plug or valve, h, upon the end of stem e, and a female-threaded cap. t', having a small aperture, j, ts over the said sleeve. Upon the upper square end of the stem is placed a handle, k, having a corresponding perforation, l, and held in place by a screw, m, iittng into'a female-threaded hole, n, in the top of the stem, and it will be seen that by the two cranks being diametrically opposite each other the inlet-valve will be opened and the waste-valve closed by turning the handle-one half-revolution in one direction, and vice versa, allowing the iluid remaining'in the cock to drain oif after the inlet-valve is closed.

Having thus described my invention Iclaim and desire to secure by Letters Patent of the UnitedStates- `l. The combination of the steni forming the two cranks,the inlet-valve hinged to one crank and the Waste-valve hinged to the other crank, arranged and operating substantially in the manner and for the purpose shown and set forth.

2. The combination of the cham berorcasing having the inlet and outlet tubes diametrically IOO opposite each other and the waste-tube in one side, the revolving stem formingthe larger and the smaller cranks diametrically opposite each other, the conical inlet-valve fitting in a seat in the inlet-tube, and hinged by its stein to the larger crank, and the waste-valve tting in a seat in the waste-tube and hinged by its stem to the smaller crank, as and for the purpose shown and set forth.

3. The combination of the revolving valveoperating stem having a laterally-'projecting piu, the sleeve having one-half of its lower portion cut away, and having the opposite outer side recessed longitudinally for the reception of the locking-pin, the upper screwt-hreaded neck of' the chamber having longitudinal recess upon its inside corresponding to the recess in the sleeve, the locking-pin f1ttingin the two recesses, and the screw-threaded securing-cap, as and for the purpose shown and set forth.

4. The combination of the valve-operating stem having laterally-proj ecting pin. the'sleeve having one-half of the lower portion cut away and the longitudinal recess diametrically opposite thereto, the screw-threaded neck of the chamber having the longitudinal .recess upon its inside, the elastic packing around the stem, the locking-pin, and the screw-threaded securing-cap, as and for the purpose shown and set forth.

5. The herein-described stop and waste cook, consisting of the chamber having inlet and outlet tubes, waste-tube, and upper packing,
